SITUATION. The arctic front that On Christmas’ Eve will have traversed Europe from north to south until leaning against the Alps, will spill over Italy on Christmas Day, generating a low pressure vortex which will be positioned in our north-central regions. A disturbance will rotate around you christmas day will cause deterioration in the central-southern regions, especially those of the Tyrrhenian, as well as in part of the lower Po Valley, while the arctic air that will begin to flow towards the central Mediterranean will also cause a lower temperatures and snow levels. On Boxing Day, the depression vortex will depart towards southern Italy and the associated disturbance will pass southward, releasing the northern skies and gradually the upper Tyrrhenian Sea, while concentrating in the south-central with bad weather and snow in mountainous altitudes. There will also be a significant strengthening of the winds caused by the low pressure vortex, as well as a significant general drop in temperatures. Let’s see the details:
CHRISTMAS WEATHER. Cold air from northern Europe will begin to flow towards Italy, generating a minimum of pressure around which will rotate a front responsible for an intensification of instability during the day, especially in the Center-South. The rains and showers will intensify already in the morning in Tuscany and northwestern Sardinia, with phenomena that between afternoon and night will extend to the lower Tyrrhenian Sea and, on the Adriatic side, the Marches. The worsening will also affect part of the North, especially in the first part of the day Triveneto, Emilia and Piedmont locally low and the interior of Liguria. Instead, the rest of the Northwest will be skipped, where the bright spots will remain. Careful with sudden fall in the snow level due to the entry of cold air. In the north, snow from 200 / 400m in the morning in the eastern Alps, snow decreases to 300 / 500m in Emilia in the afternoon, up to 1000m in the central Apennines, at higher altitudes in the southern Apennines. Lowering temperatures, especially in the Center-North. Strengthening of the west winds, from northeast to north.
CLIMATE SANTO STEFANO. The disturbance will move to the southeast remembered by the minimal pressure that will move towards the heel of the boot and the weather will definitely improve in the north and in the high Tyrrhenian SeaWith the exception of the residual instability in the morning in Romagna and Tuscany it falls with snowflakes from 400 m. Bad weather will persist in the south and in the lower-middle Adriatic with more frequent rains and showers in Marche, Abruzzo, Upper Tyrrhenian Calabria and Salento, including thunderstorms and local hailstorms in the middle Adriatic. Snow limit of 400 m on the north-central ridge, 600/800 m on the south. Temperatures in sharp decline, strong Grecale winds, from southwest to extreme south. Short respite on Sunday, but at night new disturbance that comes from the northwest with snow to the plains.
